Further, those same reports suggested that GM's European arm would wait until 2015 or so to begin UK production when the second-gen model was ready. Not so fast, reports Autocar. According to an unnamed source (aren't they all?) at Vauxhall:

There has categorically been no decision on where European production of the Ampera will take place... But in order to justify production at any European plant there will need to be sufficient demand and this, rather than the launch of the second-gen model, will drive the decision on timing.

Apparently, no decision has yet been made on where or when the Ampera will be built overseas and there's still plenty of time before the car is scheduled to go on sale in the UK in early 2011.
